So I've been looking around a bit and it looks like this typically is not a good idea as an RCA is a line level and speaker wire is not and a couple of other reasons. Well, I have an older (8 years) Sony SS-WS12 that was a part of the Sony DAV-FR1 that I want to hook up to a newer receiver that does not have a speaker wire input for the sub, but only the RCA type connector. Any way I can continue to use this subwoofer?
The speaker wire from the sub is actually hardwired to the sub and it has 4 wires that went into two connectors in the previous system. Do I need to get a new sub, or can I do some homebrewed solution? I'd rather the latter as I don't really want to buy a new sub when the old one works fine. Experts, I am asking you, am I screwed?
